Whisprun Pty Ltd v Dixon

The High Court of Australia heard an appeal from the Court of Appeal of New South Wales concerning a claim for damages for negligence. The respondent, Ms Dixon, contracted Q fever while employed by the appellant, Whisprun Pty Ltd, at an abattoir. Ms Dixon alleged that she subsequently developed chronic fatigue syndrome as a consequence of this infection. The central dispute revolved around whether Ms Dixon had established, on the balance of probabilities, that she suffered from chronic fatigue syndrome and whether the medical reports tendered in evidence had independent evidentiary value beyond the credibility of Ms Dixon's subjective account of her symptoms.

The legal issues before the High Court included whether the trial had been conducted on the basis that the evidentiary value of the medical reports concerning chronic fatigue syndrome was entirely dependent on the trial judge accepting Ms Dixon's evidence. Further, the court considered whether, if the reports had independent evidentiary value, they contained evidence of objective symptoms that could have supported a finding of chronic fatigue syndrome, irrespective of Ms Dixon's credibility. The court also examined whether the trial judge erred in not considering the medical reports as independent evidence assisting Ms Dixon's case.

The High Court allowed the appeal, setting aside the orders of the Court of Appeal. Their Honours reasoned that the trial judge had correctly determined that Ms Dixon's case regarding chronic fatigue syndrome rested entirely on her credibility, as the syndrome itself could not be objectively proven and the medical reports' value was contingent on her subjective account. The trial judge's finding that Ms Dixon had recovered from Q fever by February 1995 and was not satisfied she suffered from chronic fatigue syndrome thereafter was upheld. The Court of Appeal had erred in finding that the medical reports possessed independent evidentiary value that the trial judge had failed to consider. Consequently, the High Court ordered that the appeal to the Court of Appeal be dismissed.
